The rapid advancement of quantum computing presents an existential threat to conventional cryptographic algorithms that underpin the security of modern digital communication systems, including widely deployed email encryption standards. This paper proposes a Quantum Secure Email Client Application that integrates Quantum Key Distribution (QKD) with machine learning techniques to deliver an unprecedented level of security for email communication against both classical and quantum computational attacks. The proposed system leverages the fundamental principles of quantum mechanics through the BB84 and E91 QKD protocols to generate and exchange encryption keys that are theoretically impervious to interception, as any eavesdropping attempt introduces detectable quantum state disturbances. Concurrently, machine learning algorithms perform real-time analysis of email traffic for anomaly detection, spam filtering, and user behaviour analysis, enabling adaptive and proactive threat identification. The system is implemented using Python with Flask backend integration, React.js frontend, and standard email protocol support (SMTP, IMAP, POP3) to ensure compatibility with existing email infrastructures. System architecture comprising a QKD Module, Machine Learning Engine, User Authentication Module, and Administrative Dashboard is designed and evaluated through comprehensive testing, including unit, integration, system, and user acceptance testing. All five critical test cases demonstrate successful execution, confirming the functional correctness and security effectiveness of the proposed framework. The results establish the Quantum Secure Email Client Application as a practical and future-proof solution for secure digital communication in the emerging quantum computing era.
